<h2>Filtering Tab</h2>

<p>The Filtering tab allows you to filter the data displayed in the diagram. The first item on this tab is a 
list of colleges and majors within the colleges. When the checkbox next to a college is de-selected, all the 
college's majors are removed from the diagram, and all sub majors are disabled. Expanding the college will 
show the departments and within those, the majors. If the college checkbox is selected, you may select and 
de-select the majors within the college. When a major is de-selected, the node representing the major is removed 
from the diagram, along with all the arrows connected to it.</p>

<p>The diagram is updated as you filter, in real time.</p>
 
 
<p><b>Majors</b><br/>

<p>To filter majors, expand the section of a college and uncheck the 
checkboxes next to each major. In this example, MATH and CHEM will appear in the diagram.</p></p>


<p><b>Graduated</b><br/>
Filter based on whether the students have graduated (Yes), dropped out/transfered (No), or are still enrolled (Not Yet).</p>

<p><b>Gender</b><br/>
Choose which genders to display the data for.</p>


<p><b>Terms (Time Span)</b><br/>
To filter based on semesters and years, use the slider labeled "terms." Click one end and drag towards the center - the 
appropriate end date will update. For example, dragging the left end towards the center will change the 
beginning of the time frame (it starts in Fall 1995). The term is displayed near the appropriate end.

 <p><b>Edge Threshold (Remove Noise)</b><br/>
 Too only view significant arrows, drag the Edge Threshold slider until the highest number you wish to filter out 
 appears on the right of the slider. For example, dragging it to show a 5 would remove all edges from the display 
 with a value of 5 or less. You may also type the number directly into the box to the right of the slider.</p>

<p><b>Normalize</b><br/>
Check the Normalize checkbox to normalize the diagram over your filtered values. </p>

<p><b>Highlight Neighbors</b><br/>
When you hover over a node, the arrows going into that node will turn purple, and the arrows leaving will turn cyan. 
Clicking on the node will highlight the node and freeze the color changes until the node is de-selected. To disable 
this highlighting, use the Highlight Neighbors checkboxes.</p>

<p><b>Choose Sizes</b><br/>
By default, the diagram sizes all of its components by (normalized) raw numbers. To size by percentages, choose 
"Percent In" or "Percent Out" instead of "Number."</p>

<p><b>Auto Layout</b><br/>
When the filters are changed, the diagram is rearranged automatically. When there are many nodes being displayed, 
this may cause the program to slow down. You may also wish to move the nodes by hand. To turn off the automatic 
rearranging de-select "Auto Layout Nodes".</p>
